the coils of the electromagnet are broken by the contact 53. Under the action of the spring 54, the teeth of the coupling half 50 engage with the teeth of the coupling half of the gear 46. Thus, a rigid connection is made between the drive shaft 48 and the biscuit 44. When the workplace stops, contact 53 is closed, the measur 51 of the electromagnet 52 drawn in, the coupling disengaged and the feeding wafer disconnected.

From the galety 44 cord two-strand thread 55 enters the receiving mechanism. This mechanism (see Fig. 8 and 9) contains a drive shaft 56 carrying friction cylinders 57. On the shaft 56 is fixed coupling half 58, in the holes of which textolite plugs 59 are inserted, pressed by springs 60 to the ratchet wheel 61 fixed on the cylinder 57. On a fixed axle 62, a roar 63 is seated, on the upper end of which is an axle 64 for the package holder 65, on which a two-strand cord thread 55 is wound. The package 65 is pressed against the friction cylinder 57 by a spring 66. The cylinder 57 is rotated by a drive shaft 56 using a permanently engaged coupling 58-61. When the friction cylinder 57 stops, the electromagnet 67 is turned off and under the action of the spring 68 attached to the lever 69, the locking pawl 70 engages with the ratchet wheel 71.

After installation and threading, the receiving package holder 65 is manually guided to the friction cylinder 57. Before filling the strands on the roller 41, the device for starting and stopping (see Fig. 6) is turned off with the help of the switch 72, after charging the latter is brought into working position and starting the button turns on the spindle, the powering device-galety 44 and the friction cylinder 57.

The longitudinal shaft 48 of the feeding device and the shaft 56 of the receiving mechanism are driven in rotation from the main drive of the machine.

A cam (not shown in the drawing of the drawing) is placed in the main drive box, which drives the yarn guide 73.

At the start of the workplace, the electromagnet 67 is powered, the dog 70 disengages from the snoring wheel 71, the friction half coupling 58, which is rigidly connected to the drive shaft 56, rotates the friction cylinder 57 and the two-strand cord 55 through the eye of the folder folding machine 73 and winds onto the receiving holder 65 mechanism.
